A display apparatus including an optical component and an optical fiber component is provided. The display may include an optical component including a sensor, and an optical fiber component configured to transmit the electromagnetic transmission being incident on a front frame, to the sensor. A display apparatus may transmit light being incident from the outside to a sensor of an optical unit through an optical fiber unit, and transmits light being outputted from the sensor of the optical unit to the outside through the optical fiber unit.

Display apparatus

A display apparatus, display system, and method for displaying images thereof are provided. The display apparatus includes an image receiving unit which is configured to receive an image signal; an image processing unit which is configured to divide the image signal into a main image signal and an additional image signal and to process the main image signal and the additional image signal; a display unit which is configured to display the processed image signals; an image projection unit which is configured to project the processed image signals; and a control unit which controls to provide the processed main image signal to the display unit and the processed additional image signal to the image projection unit.

Display apparatus, display system, and method for displaying image thereof

A radar system includes a transmitter stage for generating a certain transmission signal; a circularly polarized antenna for emitting the transmission signal in a form of a circularly polarized signal, and receiving a reflection signal; a polarizer for isolating the reflection signal received from the circularly polarized antenna from the transmission signal, and outputting the reflection signal to a next stage; and a receiver stage for receiving the reflection signal output from the polarizer, converting the reflection signal into a signal of a certain frequency by using as a certain mixer switching signal the leakage signal leaking from the transmitter stage, and outputting the converted reflection signal. Therefore, the high-sensitivity radar system can be built in a compact size.

Radar system having single circularly polarized antenna

A radar system using a quadrature signal includes a quadrature push&#x2014;push oscillator for generating four harmonics with a 90-degree phase difference from each other, and producing two-balanced 2harmonic signals from the harmonics; a first coupler block for radiating one of the 2harmonics through an antenna; a second coupler block for terminating the other 2harmonic to ground; and a power combiner for combining a transmitted signal that is leaked from the first and second coupler blocks with the received signal that is radiated through the antenna. The radar system features an improved receiving sensitivity by offsetting the leakage signals of the sending end. Also, the radar system can be made very small by using a single antenna for transmitting and receiving.
